Abstract: An improved carpet dryer is disclosed for drying carpets saturated with water. The dryer includes a securing mechanism for maintaining the edge of a carpet on the upper surface of the air outlet portion of the device. The device further incorporates a shroud disposed on one air intake of the dryer to minimize the effects of air turbulence within the dryer unit.

Abstract: A heating apparatus comprises a closed vessel having thermally conducting walls and containing a gas that is heated by one or more electrical heating elements in the vessel. The vessel is received in a duct through which air is blown. The air is heated by the heat transferred to the vessel walls by the gas in the vessel. Pressure and thermostatic switches in the circuit of the heating element communicate with the gas in the vessel and provide a double-safety, over-temperature power shut-off. The heating apparatus may be used to blow hot air into water in a tub through hoses leading to inlet openings or to an air distribution mat placed in the tub. The bubbles of hot air heat the water and produce strong agitation. A special raft receives the air distribution mat, which heats water in the raft by bubbling hot air through it. The heating apparatus can also be used for space heating, warming and drying towels and clothes, hair drying and grooming animals.
